Iltwardly of the knives` 38 is a straight knife 1li) ix tending entirely across the plate, which knife coperstes throughout certain portions thereof with grooves 39'* of the roll to forni scores or indenlntions indicated by the lilies 39 in Fig. 9. 'lhegrooves 3U ofthe roll do not extend continttonshv across tht` hitter, as' shown in Fig. 3, being interrupted, und whore the knife 39 engages the Solid portions oi .the roll between said grooves it obviously cuts they blank entirely through, as ilidieitted by the lines 39" in Fig. 9. A similar knife 40 coperates with similar grooves 4U in the roll to form the indentations 40 and cntsAO. Another kniictell co Operates with a groove 4l extending the inll length of the roll, as shown in l"ig.3,t.ofor1n the scores 4l. Still another sectional knife 42 cnperntcs with an interrupted groove 42 to forni the scores 42" in the blanks; and, finally, a straight knife 43 cooperates with the solid surface oi the roll to forni the end cut oi the complete blank indicated by the line 43. The roll-engaging faces of the tables also carries certain other knives forming the longitudinal and oblique cuts and indentntions of thiI blank. The knives o the die-plaint` which forni said longitudinal ents and indentntions are indicated at 44, in Fig. 5, certain of these last nalnt'd knives' coperating with the solid periphery oi the roll to forni the side cuts 4-1, and others cooperating partially with solid portions and partially with grooved portions of the periphery of the roll,rto forni the intermediate cuts 44 and scores 44. As indicated in' Fig. 5 the plates are still further provided with oblique and irregular shaped knives, shown in ctlssstetioii at 45, 4G .'l'fid 47, respeo tively, in Fig. 5 and arranged at varying angles to each other, which knives eoperate with solid portions nl the roll to cnt ont the irregular shaped parts indicated by the spaces 45, 4G and 47', respectively, in Fig. 9, whereby the end flaps ol' the eartmt blank are given a formation adapting them to he folded and interlockcd in setting up the carton. As `shown in Fig. 5, those portions of they space of the plates bounded by the knives which create the irregular excisions of the blank, indicated by the spaces 45, 46 and 47 are cnt ont through to the spaces formed by the hollow slides of the dieplatvs; and said spaces are sueetssively brought into communication at one end with a pipe 48 through which compre sed air is forced, su that the scrap o the blank that lotlges between the knives is blown out and discharged as the plates are undergoing their return movenient ont the under side ol the sprockets, lor which purpose the end o1' the hollow plates opposite to the end which is in communication with the nir pipe is Llosed against the escupe ot air therefrom as by sliding over a .stationary closure indicated by Li!) in Fig. .'5.

The periphernl surfnetol the roll, its herein shown, is adapted to the formation oi three elldwse :nliittenl blanks on euch quartet' surface, making twelve bhlnks in all that niny be eut by each complete rotation oi the roll.. lt is also to be understood thnt those |inrtio1is.oi thiI knives which merely eoperntey with the grooves oi the roll to score or indent the sheet ure lornled with a dull or bltlilt i dge, soas toavoid the cutting oi tlnasheet, while other portionsl of said knives which e lliect the entting and the slitting of the sheet. are, of course, provided willi sharp cutting edges.

For convenience in handling and stacking the cut and scored cartons as they ure. delivered by the inaehine, it s desirable that. when delivered, they be not entirely separated, but be attached ut one or two points so as to be easily separable later, when the in dividual cartons are to be set up. This result nitty be attained in the present machine by simply nicking, at intervals, all but one of the knives 43 which form the divisions between successive endwise adjacent series of carton blanks, thereby leaving said blanks, in groups of twelve, connected by thin integral tongues or strips, indicated at 43"- in Fig. 9.

50 designates a series of rubber buttons sc t at intervals into the outer face of each of the plates 23, and supporting the blank sheet as it passes beneath the die-roll. These buttons, being of elastic material, yield readilyto the pressure of the roll; but when the sheet has' passt-'d the latter and the blanks have been cnt and detned, the resiliency of the buttons operates tn raise the blank ofi" the knives and render it free to drop down over the guard 5l (Fig. 2) onto a discharge conveyer 53. i i

l 54 and 55 designate a pair of embossing or printing rolls suitably mounted in and between the side frame members of the machine between the die'roll and the reel or other source (not shown) from whence the blank sheet is delivered to the machine. Said rolls may conveniently he driven from the gear 19 through an ntermediate gear 56 engaging the lower roll-pinion 57 said pinion driving a companion pinion 58 on the upper roll 54.

In a machine of this character it is essential to be able to secure perfect registration between the coperaling rotary and rectilinear die-members, and more particularly perfect registration between the coperatl ing knives and grooves which effect the scores or inflcntations. 1n order that the roll may be readily set to bring its peripheral grooves into exact rgistration with the knives of the die-plates, I provide' the aidjusting means shown in Fig. 1, wherein 59 designates a pair of ears fast on the face of th gear 37, carrying set-screws 60 which engage opposite sides of a lng 61 on the adjacent face of the roll, thereby enabling the roll to be set to a fine angular adjustment relatively to its driving gear. In order to effect` the proper adjust ment of the knife edges to the surface of the roll for the cutting operation,l so as to cnt through the sheet Without turning or dulling the edge of the knives, I provide inem iur ihn-ly :nlhlsting the height of 'lle diefnll allow lin4 tlmlrrl). inf.; (lie-platea. such means, as herein .-h:1\i'||. volaipl'isillg :i migo UL (Fig, l) underlying ille xpiil juin-intl 2th on each ein] ni the roll, l1nd adjustable lnwnrdli und entntnlil'f by :l hand Wheel |33 Luhfierat` ing with n srrmvlln mhh-d rnd [jfl instituting the stem nl' lin* wedge.
